When you first open Streamlabs OBS for the first time after you've gone through the install, you will be asked to login with your streaming account.


Click on “Setup later“ and you will then be presented with your editor. For the next step go to "Settings" at the top right corner to configure your client:

Open the "Stream" tab to access the stream settings:

Setup your Stream

Under the Service tab, click on “Show all services“ and choose "Picarto". Remember to choose a server that‘s based in your region.

Once you're logged into Picarto, click on the "Go Live"  Your stream key will be displayed be clicking the "Show" button. You can copy the stream key by clickling on the "Copy" button. After that paste your copied stream key into the "Stream Key" section.



After you put in your Stream Key you can proceed with the "Output" settings on Streamlabs OBS.

Output Mode: Simple

In the “Simple“ output mode you can edit all the settings essential to stream, such as the video/audio bitrate and encode. You can start your livestream by setting the “Video Bitrate“ to 350. If the stream quality is not good enough for you, you can increase it later on. Please keep in mind that higher bitrate requires a faster internet connection.

Output Mode: Advanced

1. Please choose x264 Encoder and Use CBR.

  • If you display fast movements during your streams (such as animations) you can also disable CBR to save bandwidth.

2. Max bitrate should be set according to our streaming standards, but not more than 3500. Please keep in mind that your bitrate should not be higher than your own internet upload speed, otherwise you will suffer frame drops.

To find out your upload speed, you can do a speedtest at: http://www.speedtest.net/

We recommend the following bitrates for different resolutions:

Your Upload


Bitrate in kbit/s

Keyframe intervall

under 1 Mbps


350 - 500


1.5 Mbps - 5 Mbps

720p -1080p

500 - 800


over 5 Mbps

1080p - 4k

1000 - 2000


If you have a very slow connection to begin with, set the Keyframe intervall to 4 or 8. Be aware that this will increase your video loading time, but will guarantee a more stable stream.

After you have configured your output settings you can proceed with your "Video" settings:

Output (Scaled) Resolution is the final resolution you are sending to our servers. If you choose lower resolutions this can help reducing your processing (CPU) power as well as the use of bandwidth.

FPS can remain at 30, but it's also possible to lower them down to 24 to save CPU processing and bandwidth.

Now you can click on the "Done" button at the bottom right to close the settings window and start your first livestream on Picarto.
